Abstract
A wood cutting or scarfing and wood sawing apparatus includes a power saw having a pair of mutually spaced scarfing blades positioned in advance of the saw blade and aligned with side edges thereof. The scarfing blades, spring urged into engagement with a wood article being cut, sever surface fibers of the article in the cutting path of the following saw blade. Because the surface fibers are previously cut by the scarfing blades, the saw blade, which may thus be of a conventional crosscut type, does not tear the surface and a clean, smooth edged cut is provided. The apparatus is particularly adapted to laminated wood articles, such as conventional hollow core doors and plywood panels and sheets, which are otherwise difficult and relatively time consuming to cut without splintering. To enable cutting of doors and large panels or sheets, a large article support structure and a saw guideway are provided.
